The Wildforce Megazords come from the Japanese sentai show Gaorangers.
The original Japanese name of this toy is Gao Icarus.

If you are looking for play value, the Isis Megazord satisfies in every
way. Press a button on the giraffe, and the Gao Spear extends. A similar
button on the deer activates the Gao CrossHorn (the antlers move). You
can turn the armadillo into a ball and use the spring action of the rhino?s
horn to kick it across the room. Also, the wings of Isis fold over to
create "Ultimate Defense Mode".

Isis is fairly straightforward to transform. The deer and the giraffe
simply fold in the legs. The most challenging part is the rhino, but once
you do it once you don't forget it.

The Isis Megazord is very similar to its Japanese counterpart, Gao Icarus.
All of the die cast metal parts remained intact, although some of the
paint detail is missing for the US version. Bandai has made big improvements
in the US versions of its toys since the early days of the Mighty Morphin'
Power Rangers.
